The stocks remained unassessed, and a few TURFs had already been closed in the past due to signs of stock decline. We built a database of weekly catch, effort, and weight data using fish auction records and biological sampling to apply intra-annual generalized depletion models to a single fishing season (2021/2022). The models identified two positive pulses: one in early autumn and another during the Christmas period, related to the scheduled annual reopening of closed fishing grounds. All TURF fisheries had a proportional effort response and were hyper stable with respect to barnacle abundance.

However, financial resources for monitoring are often limited and must be allocated between competing priorities. This problem is acute for fisheries management, where harvest limits are ideally updated to track changes in population abundance, but the number of populations in need of monitoring often exceeds the available capacity. Here, a bioeconomic model was used to identify the optimal strategy for investing in fisheries monitoring programs, such as surveys and stock assessments. A sensitivity analysis identified factors to prioritize scarce fisheries monitoring resources. Monitoring contributed up to 20% of the total net present value of the fishery. Value largely flowed from increasing fisheries profits, rather than non-consumptive values, and was larger for populations with fast growth rates and large relative abundance. The model predicted large economic values for fisheries monitoring programs because they created stabilizing feedback to maintain the population in a productive, economically valuable state. The optimal policy tuned this feedback mechanism to match stock dynamics and economic potential of the fishery.</p>\u0000 </div>","PeriodicalId":50444,"journal":{"name":"Fisheries Management and Ecology","volume":"33 2","pages":"368-378"},"PeriodicalIF":2.0,"publicationDate":"2026-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147562765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used an ECOPATH with ECOSIM model that was calibrated for 2000–2016 to simulate ecosystem effects through 2025. A reference scenario (Sc0) for current fisheries and discarding practices in the gulf was used to compare with simulated discarding scenarios. Two scenarios simulated enforcement of the LO after the calibration period, including one that considered all functional groups with available commercial fisheries catches and one with species subject to minimum conservation reference size. Two other scenarios tested different discarding management practices, during which discards were reduced to zero. All scenarios demonstrated smaller impacts on commercial marine species and larger impacts on species that rely on discards as their main food source.

These systems offer significant advantages in data collection efficiency and coverage compared to traditional monitoring methods, but present complex technical, analytical, and societal challenges that require innovative solutions. Current developments in camera monitoring technology highlight advances in hardware reliability, data management infrastructure, and artificial intelligence (AI)-powered analytical capabilities that transform raw visual data into actionable management information. Key challenges include hardware constraints in marine environments, massive data storage and processing requirements, integration with existing management frameworks, and privacy considerations. Recent technological developments, particularly AI and edge computing, offer promising solutions for automated analysis, behavioral pattern recognition, and cost-effective data management. AI-powered computer vision systems enable automated angler counting, activity classification, and catch event detection, while edge computing capabilities provide real-time processing and alert generation without requiring constant data transmission. Integration of drone-based monitoring technologies with fixed camera systems adds opportunities for extensive spatial coverage while highlighting regulatory and operational challenges that must be systematically addressed. Successful implementation of effective camera-based monitoring systems requires addressing institutional capacity constraints, particularly when resources limit technical expertise, computational infrastructure, and financial resources that may be inadequate for full-scale deployment. Of critical importance are interdisciplinary collaborations among fisheries scientists, computer vision researchers, and statistical data scientists in realizing the full potential of these systems. Critical areas for future development include robust hardware solutions, scalable data infrastructure, standardized analytical frameworks, and inclusive governance structures. Continued advancement in this field will depend on supporting equilibrium between monitoring effectiveness and ethical implementation through participatory approaches, standardized protocols, and capacity-appropriate deployment strategies.</p>\u0000 </div>","PeriodicalId":50444,"journal":{"name":"Fisheries Management and Ecology","volume":"33 2","pages":"282-297"},"PeriodicalIF":2.0,"publicationDate":"2026-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147564793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Must-kill regulations, which prohibit the live release of invasive fish caught by recreational anglers, are a management strategy that can be implemented to limit the negative effects of invasive fish populations. Our review of angling regulations around the globe revealed that must-kill regulations for numerous species were frequently enacted in countries including Canada, Japan, and the USA. Suggested benefits of must-kill regulations included limiting invasive species population size and preventing their dispersal, among others. While these benefits were plausible, we found no rigorous assessments of their effectiveness. Moreover, must-kill regulations can introduce concerns such as angler opposition and species misidentification. Here, we bolstered sparse evidence with anecdotes and perspectives to identify potential advantages and drawbacks of must-kill regulations. We also provided guidelines for implementing must-kill regulations that emphasize strategies to increase the likelihood of success while minimizing unintended consequences. Specific guidelines vary depending on management objectives, but generally include a preliminary feasibility and risk assessment followed by post-implementation monitoring of efficacy and consequences.</p>","PeriodicalId":50444,"journal":{"name":"Fisheries Management and Ecology","volume":"33 2","pages":"260-270"},"PeriodicalIF":2.0,"publicationDate":"2026-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/fme.70021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
